Page 6: Safety, Codes And Regulations
1. Safety, Codes and Regulations Thank you for the purchase of an EnergyLogic used oil heater. EnergyLogic heaters are designed and tested for safe, reliable long-term operation. However, proper installation, fuel quality control, and regular maintenance are required. Please read and understand this manual completely before attempting to install, operate, or service the heater. -
Page 7: Safety Hazards
Only those qualified should perform the tasks. Specific safety hazards include: Electricity: The EnergyLogic heater operates on 115V/60Hz electrical power. Turn power off at the circuit breaker and lock it out prior to performing any work on the heater system or any of the components. - Page 8 Height, Weight, Guarding and General Safe Practices: The flue pipe for these heaters are installed at heights which pose a risk for injuries due to a fall. Many of the components are heavy, and pose the risk of injury with improper lifting and handling. Always follow safe practices and use proper equipment.

Page 9: Codes And Regulations
1.3 Codes and Regulations The installation, operation, and maintenance of the heater system in the United States must be performed by qualified personnel in accordance with this manual and all national, state, and local codes / regulations, as well as the following standards of the National Fire Protection Association (NFPA): NFPA 31 Standard for the Installation of Oil Burning Equipment... -
Page 10: Fuels And Fuel Management
In order for the system to function as designed, good fuel management practice must be followed. The 75H heater is listed by Underwriters’ Laboratories (U.L.) for the U.S. and Canada, operating on the following fuels: • Used Crankcase Oil. -
Page 11: Clearances To Combustible Surfaces
1.5 Clearances to Combustible Surfaces It is of the utmost importance that the installation conforms to the minimum clearances to combustible surfaces (Material made of or surfaced with wood, compressed paper, plant fibers, plastics, or other material that can ignite and burn, whether flame proofed or not, or whether plastered or unplastered). -
Page 12: Installation Considerations
2. Installation EnergyLogic heaters are designed to operate reliably over a wide range of conditions. However, proper installation is required to prevent unnecessary rework or problems. 2.1 Technical Guidelines All components of your heater are factory-tested to ensure proper operation. Do not tamper with controls. -
Page 13: Drain Valve Installation
Minimum Clearance – Safe clearances to combustibles (Section 1.5) shall be adhered to. Distance from Flammable Liquids – Do not create a fire or explosion hazard by using or placing flammable liquids such as gasoline or solvents near the heater. A flammable liquid is any liquid that has a closed-cup flash point below 100°F (37.8°C), as determined by the test procedures and apparatus set forth in 1.7.4 of NFPA 30. -
Page 14: Exhaust Flue System Installation
• Review this section completely. Choose and purchase a factory-built flue kit that complies with U.L. standard 103 Type HT, or Equivalent. • The 75H requires a 6-inch diameter flue and may not be reduced. • For your convenience, the unit includes some helpful chimney-flue material. Additional material will also be necessary. - Page 15 2 feet higher than any portion of a building within 10 feet (NFPA 31, 54 and 211 – see figure). For increased margin, EnergyLogic recommends extending the flue further than the minimum guidelines. • Minimum stack height: 10 feet, plus 1 foot for each NFPA rules for flue height above roof additional tee or elbow.
- Page 16 There are other possible causes as well. Corrective measures must be taken before operating the appliance if the correct draft setting cannot be achieved. Contact EnergyLogic or consult a local professional for assistance.

Page 17: Draft Gauge Installation (Included With Some Packages)
3.3 Draft Gauge Installation The draft gauge is a precision inclined-vertical manometer. Permanently installing the draft gauge allows you to monitor the draft during operation. Installation Mount and level the draft gauge to the heater cabinet using the screws provided with the gauge (refer to figure). -
Page 18: Electrical System Installation
4. Electrical System Installation Power requirements: a dedicated, hard-wired 115VAC/60Hz circuit with a 10 Amp (15 Amp max) circuit breaker. Use copper conductors only. A wiring diagram is provided in the Appendix. Electricity is very dangerous. Wiring should be completed by a qualified electrician. -
Page 19: Main Electrical Connection
4.2 Main Electrical Connection Personally verify that the main circuit is OFF and Locked-Out before making any wiring connections. Use only copper conductors. All wiring installations should meet National Electric Code (NEC) and local guidelines. Canadian wiring installations should be done in accordance with the Canadian Electrical Code, Part I. -
Page 20: Startup And Operation
5. Startup and Operation Once setup properly, EnergyLogic heaters are designed to operate reliably over a wide range of conditions with minimal adjustment. This section is provided to make sure that the heater is set up properly, and to provide instructions on the initial startup. -
Page 21: Safety Systems And Warnings
Multiple resets may allow fuel to accumulate in the heat exchanger, therefore do not reset more than one or two times without diagnosing the issue. Call EnergyLogic for technical support. DO NOT ATTEMPT TO START THE BURNER WHEN EXCESS FUEL HAS ACCUMULATED IN THE CHAMBER, WHEN THE HEATER IS FULL OF VAPOR, OR WHEN THE COMBUSTION CHAMBER IS VERY HOT. -
Page 22: Heater Startup
5.4 Heater Startup Prior to the initial startup of the heater, make sure the power has been on at least 10 minutes for the nozzle block to heat up. Once the burner is operating, the system should be checked and necessary adjustments made. It takes some time for fuel to reach the nozzle and push all the air out of the system. -
Page 23: Burner System Checkout
5.4.2 Burner System Checkout Once the heater starts operating, make the following checks and adjustments: If you are unable to obtain the proper adjustments, do not run the heater. If you cannot resolve the issue, call Technical Support for assistance. Fan Operation: Within the first few minutes after the burner fires, make sure that the fan begins to operate and directs warm air into the room. - Page 24 Note: The draft gauge should read 0.0 inches of WC when the probe is removed from the stack. (If not, make sure the gauge is level, and readjust the zero knob). If the heater is not running, the draft gauge with the probe installed into the stack will not necessarily read zero, depending on ambient conditions.
- Page 25 Air Pressure: The burner has a built-in air compressor to provide pressurized air for oil atomization at the nozzle. The air pressure is set at the factory to 4 psi. If the pressure has drifted and a pressure adjustment is required, loosen the 3/8” nut on the bleeder valve, adjust the stem with a small screwdriver, and tighten the nut to lock it in place.

Page 27: Maintenance
Only those qualified should perform these tasks. 6.3 Monitoring System Performance over Time EnergyLogic recommends that you monitor and record your system gauge readings regularly over time, in order to diagnose issues that may arise. For example, if the pump vacuum gauge initially reads 2 inches Hg, but over time has risen to 10 inches Hg, it is an indication that the fuel filter is most likely clogged up. -
Page 28: Maintenance Procedures
6.4 Maintenance Procedures The following sections provide detail on how to perform the recommended maintenance. If you have questions or need assistance, contact Technical Support. Inspect Remove ash compressor every 1000 and replace hours or at air filter the end of annually every heating season. -
